Abstract: A patient interface device (8) that includes a cushion (12) structured to receive a flow of treatment gas, a frame (14) having a central portion (17) structured to couple with the cushion and a strap (18a, 18b) extending from the central portion, a headgear component (28) including at least one of a top portion (30) adapted to fit on top of a patient's head and a rear portion (32) adapted to fit behind the patient's head, and a coupling mechanism (34a, 34b) structured to couple the strap to the headgear component, wherein an end portion of the strap is structured to pass through an opening in the coupling mechanism, fold back in a direction toward the central portion of the frame, and releasably attach to the strap, such that pulling the end portion of the strap toward the central portion of the frame tightens the patient interface device.

Abstract: A nasal prong for a cushion member for use with a patient interface device that includes a casing, a flap extending from the casing for insertion into a nostril of a patient, and a bottom cap. The casing and the bottom cap define a space. A fill material is disposed in the space defined by the casing and the bottom cap, wherein the casing is structured to deform and conform to a shape of a portion of the nostril when the nostril applies pressure to the casing.

Abstract: A pressure support device (4) includes a sensor (32;32?) structured to gather data on one or more medical parameters associated with a non-sleep disordered breathing medical condition, a processing unit (31;31?) structured to analyze a risk of the non-sleep disordered breathing medical condition, and an indicator (38) structured to alert the patient when the risk exceeds a predetermined threshold level.

Abstract: A patient interface device (8) that includes a cushion (12) structured to receive a flow of treatment gas, a frame (14) having a central portion (17) structured to couple with the cushion and a strap (18a, 18b) extending from the central portion, a headgear component (28) including at least one of a top portion (30) adapted to fit on top of a patient's head and a rear portion (32) adapted to fit behind the patient's head, and a coupling mechanism (34a, 34b) structured to couple the strap to the headgear component, wherein an end portion of the strap is structured to pass through an opening in the coupling mechanism, fold back in a direction toward the central portion of the frame, and releaseably attach to the strap, such that pulling the end portion of the strap toward the central portion of the frame tightens the patient interface device.

Abstract: A nasal prong (26) for a cushion member adapted for use with a patient interface device that includes a casing (134,136), a flap (132) extending from the casing and being adapted to be inserted into a nostril of a patient, and a bottom cap (138). The casing and the bottom cap define a space. A fill material (140) is disposed in the space defined by the casing and the bottom cap, wherein the casing is structured to deform and conform to a shape of a portion of the nostril when the nostril applies pressure to the casing.

Abstract: A patient interface device for delivering a flow of breathing gas to an airway of a patient, comprises a mask component and auto-adjusting headgear. The auto-adjusting headgear comprises one or more straps wherein the materials have elasticity characteristics such that the headgear self-adjusts. The headgear comprises two lateral strap sections, a rear strap section, and a top strap section. The strap sections are of varying materials and thicknesses to control the properties of the strap sections. In one embodiment, at least a portion of a strap includes a high friction material disposed so as to contact a portion of the user responsive to the headgear being donned by a user.
